Description

ROLLER APPLICATOR WITH BREATHER FIELD OF THE INVENTION The present invention relates to a roller applier, the gripper according to the present invention, and the leakage between the inside and the outside of said applicator.

LU BACKGROUND OF THE INVENTION Roller applicators are well-known in the art. Usually, said applicators are containers that include a hollow body for liquid, a ball and a means 5 support retainers for said ball. These roller applicators allow < Apply a liquid film from the inside of the hollow body to a selected surface. The common problem of these is to avoid the draining and spillage of the liquid contained during the periods that said roller applicators are not used. The prior art solves the problem by using the joint operation of a lid. Indeed, as described in E.U.A. 3 036 328, E.U.A. 4 221 494, E.U.A. 4 221 495, E.U.A. 4 475 837 and E.U.A. 5 051 107. the ball is forced to interconnect with and lean against a sealing surface of said support retainer means when the container is closed with the lid. But this solution to prevent draining and spillage is inconvenient, if the aforesaid means for supporting the ball is located below the level of the contents. In effect, l may occur. Drain or spill during the operation of unscrewing the lid. For this reason, the roller applier of the above device has the ability to hold the ball holder retainer means only on top of the corresponding surface above the contents when the LU stores said container in its vertical position. Another disadvantage of the rollers The previous technique is given by the fact that the quantity of application can not be increased. Instead, the prior art teaches only about a decrease in said application amount. Indeed, the roller applicator means described in the aforementioned prior art can force the ball to interconnect with and lean against a sealing surface of said support retainer means to decrease or completely stop the flow of content. on said ball. The reverse is never possible .. On the contrary, an increased amount of application is useful especially during the pretreatment of stain on a fabric. In effect, different spots may need more - amount of liquid detergent for a pretreatment effective. For example, the stains formed from various constituents may need a greater amount of detergent to achieve a more complete and effective pretreatment. A larger amount may also be needed to simply cover the size of the spot. The above problems have been solved with the applicator disclosed in European Patent Application No. 94870179 2. Said roller applicator includes a container adapted to contain and dispense a product. Said container includes a hollow body, a dispensing opening, a ball and flexible and resilient support means for said ball. Such flexible and elastic support means push said ball against said dispensing opening, achieving a leak tight interconnection between said ball and said dispensing opening. Said flexible and elastic support means can be elastically deformed by any external force acting on said ball, thereby eliminating said hepnetic interconnection against spills between said ball and said dispensing opening, allowing said content product to be applied. for that ball. In practice, said flexible and resilient resilient means together with said ball acts as a valve that opens when it is pressed on said ball. Be noted that said ball pushed against said dispensing opening by said flexible and elastic support means, also achieves a hermetic interconnection to gases. Next, "gas-tight interconnection" means that gases can not pass through the interconnection between the internal delivery and the external delivery of the newborn. Alternatively, "airtight connection to gases" can also mean that the proportion of pressure that can be released to the outer part of the container through this interconnection (hereinafter referred to as "pressure release rate"). ) is as small as the proportion of pressure produced inside said container. Therefore, a pressure of said container is formed, because the amount of gases that can unclog the outer part of said container is too small with r-spectra to the pressure formed inside said container. There are a number of possible factors that can lead to the existence of pressure formed within said container. The contents of the package, for example, may be chemically unstable or may be subject to reaction with the gases that may exist in the upper space of the package, or alternatively, in certain specific circumstances, they may act as material of the same package. Any chemical reactions that involve liquid contents can lead to the production of gases and therefore to the overpressure in the package. Pressure formed within said container may also occur when the temperature during filling and container sealing is significantly different from the external temperature during shipping, transport and storage. Another possibility of differential pressure may be caused by a different pressure of the environment in filling the container with another pressure from the environment in a different geographic location. It was observed that the liquidity with the gases between said ball and said opening is further increased although the pressure release rate is further reduced, when the pressure is formed inside said container. In effect, this internal pressure further presses said ball against said dispensing opening further reducing the rate of pressure release. The rate of pressure release can be reduced to almost no pressure release at all. It was further reported that the product can be expelled outward when pressure has been formed within said roller applicator described in the pending European Patent Application 94870179.2. To apply the product contained around the ball, it may be necessary to invert said container to bring said product to said ball. This is not necessary, if said ball together with said flexible and elastic support means are located below the filling level of said product. However, in both cases, when pressing on said ball a free path between said ball and said dispensing opening is created. Therefore, the gas formed within said container tends immediately to escape through said path, like a burp. Accordingly, the product located between said formed gas and said free path can also be expelled quickly and uncontrolled. This rapidly expelled product creates dirt and debris. In effect, the expelled product can also cover other areas that the user did not intend to cover. In addition, the quantity of product expelled may be more than necessary without 1 a pos i bi lity.; It is therefore the object of the present invention to provide a container against the drains which includes a roll applier, but which nevertheless allows the gases to escape to prevent the product from being expelled from the inner part of said container and pressed by the pressure formed inside the container thus avoiding dirt and waste of the contained product.

BRIEF DESCRIPTION OF THE INVENTION The present invention is a package that includes a container (10) adapted to contain and dispense a product, and a lid (20). Said container includes a hollow body (1), a dispensing opening (2), a ball (3) and flexible and elastic support means (4) for said ball. Such flexible and elastic support means push said ball against said dispensing opening, achieving a substantially leak-tight interconnection between said ball and said dispensing opening. Said flexible means and supporting st cle can be deformed in a clastic manner by an external force acting on said ball thereby eliminating said substi cially hermetic interconnection between the said ball and said dispensing opening, allowing said pr - Content pipeline is applied by said ball. Said lid can interconnect with said container removably. Said lid covers said dispensing opening. Said unit presses on said ball creating a free path between said hello and said dispensing opening only when said cover is interconnected and / or disconnected from said receiver.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the container 10 according to the present invention is shown in a cross-sectional view in Figures la and Ib. The present invention provides a container 10 (used only partially in Figure 1) adapted to contain and dispense a product. The word "container" encompasses any shape and / or type of container including a hollow body 1 and a dispensing opening 2. For example, bottles, tubes, dosing devices and / or dispensers are containers according to the definition of the container. present invention. The hollow body 1 of the container can be made of rigid, soft or flexible material. Soft or flexible materials may be preferred to allow the hollow body itself to be tightened for even more controlled dispensing through the opening. Specifically for the dosing and / or dispensing devices, said hollow body can be made preferable from a material resistant to water temperatures of up to 95 ° C. Such dispensing opening is located in the upper portion of said container. Next, "upper portion of said container" is the portion of said container from said dispensing opening to the highest level of the contained product when said container is in its vertical position or is the neck when said container is, for example, a bottle. Furthermore, the "axis of a container" is a direction perpendicular to the base on which said container is in its vertical position. Specifically, said dosing and / or dispensing devices are adapted for the pretreatment of tissues, such as, for example, that described in UO 92/09736 and / or WO 92/09736. Usually, such dispensing device and / or dispenser adapted for the pre-treatment includes an additional opening that allows the filling of this device. lü When this device is placed inside the washer-a with the tissues, such a filling aperture also allows the dispensing of the washing liquid content of the machine during the washing cycle. The filling opening is usually located on top of said dosing and / or dispensing device when said device is in its vertical position. A partially or completely transparent hollow body 1 is a preferred option to allow the user to verify the amount of the content and to facilitate measurement and dosing with dosing and / or dispensing devices. As a further preferred option said container may have an upper portion that is inclined with respect to the rest of the hollow body, i.e. said dispensing opening is not along the axis of said container. In this way, the required angle of inclination for dispensing said contained product through said dispensing opening can be reduced. As another preferred option, such hollow body may further include a metering line on the surface and / or interior of said hollow body (Figure 4, 11). Preferably, said container is made of plastic material, such as, for example, polypropylene, polyethylene, polyurethane or polyvinyl chloride. The container 10 can be adapted to contain liquid substances. Preferably, said product is a liquid detergent. In accordance with the present invention, the liquid detergent may include any ingredients known in the art. Such ingredients may include surfactants, suds suppressors, bleaches, chelators, builders, enzymes, fillers and perfumes. An essential feature of the present invention is a ball 3. Said ball is located partially in said hollow body l in dispensing opening 2, that is to say said ball projects at least partially from said dispensing opening, that is, said ball is located in the upper portion of said container. The dimensions of said ball and said dispensing aperture are adjusted to each other so that the ball can not escape ovally through said dispensing opening to the outside of said hollow body. In use, the content of said container is applied by said ball, since said ball is always in communication with the contents of said container 10. In use, part of the content is put in contact with said ball and is then applied on a surface force of said container by the rotation of said ball. Said ball 3 may be hollow or solid, and may have a generally smooth outer surface or may have an outer surface having a certain degree of roughness. Said ball may be formed of an open or closed cell structure. Privilegedly, said ball is rigid. The use of a spherical ball allows a unidirectional application, since a spherical ball will rotate in any direction with equal efficiency, if said spherical ball is not fixed on an axis. Other forms of said ball may be used, such as, for example, cylindrical or ellipsoid. But such shapes may have functional limitations in the sense that the balls of those shapes will only rotate generally around a single axis. Preferably, the present invention uses spherical balls to allow unidirectional application. It has been observed that this is particularly useful in order to achieve a precise and convenient application of liquid detergent during the previous period, without considering the patterns of the stains. On the contrary, if the ball were to be rotated around an e, the user would be forced to perform complicated movements with the hand, as well as twisting the wrist. The application with a unidirectional hello of rotation is also controlled better and therefore avoids the waste of liquid detergent, since it is easier to apply only on the limited area of the stain. Specifically for dosing and / or dispensing devices, such a ball may preferably be formed of a material resistant to water temperatures of up to 95 ° C. For example it is possible to use plastic materials, such as, for example, polyethylene, polypropylene, polyurethane or polyvinyl chloride. The ball 3 is manufactured independently of the hollow body 1. This ball can then be inserted through said dispensing aperture to said flexible and elastic support means simply by pushing said ball through the lip 9 of said dispensing aperture. This is possible, since said lip 9 of said dispensing opening is suffi- ciently flexible to deform the sticamen e at least lightly, since said lip, part of the hollow body or of the flexible and supporting support means, is preferably made of plastic material The container 10 can also include more than one ball J, independently contained in different dispensing openings 2 with a common dispensing aperture The flexible and elastic supporting means 4 for said ball is another essential feature. of the present invention Three flexible and elastic support means push said ball 3 against said dispensing opening 2, during an interconnection n sealing between said ball and said dispensing opening. According to the above, said flexible and elastic support means close the dispensing opening with the cooperation of said ball and are located in the upper portion of said container. In a preferred embodiment, said flexible and elastic support means press said ball against the outermost lip or lip 9 of said dispensing opening. It was observed that the interconnection between said opening 2 and said ball caused by said flexible and elastic support means is substantially leak-proof of the liquids. Then, "substantially leak-tight" means that said interconnection between said ball and said dispensing opening is resistant to the flow of the product when the only force exerted on said product against said interconnection is constituted by the hydrostatic pressure. Therefore, it is possible to avoid draining or substantial spillage during periods when said container 10 is not used, but rather cooperation of a lid. As a preferred option, said lip 9 of said flexible and elastic support means 4 are flexible. or deforrnables. In this way, the flexible or deformable lip can be formed with and / or compensate for any imperfection in the shape of said ball, for example when said ball does not have a perfect spherical shape. To achieve this, said flexible or deformable lip may be made of a separate material attached to the perimeter of said dispensing opening. Said flexible or deformable lip of said flexible and elastic support means may also be formed projecting the flexible or deformable material, such as rubber, forming said lip together with a rigid material for the rest of said flexible and elastic support means. A flexible or deformable lip will not affect strength and / or structure of said flexible and elastic support means. Said flexible and elastic support means (4) can be elastically deformed by an external force acting on said ball 3. According to the above, pushing said ball into said interior, said substantial and hermetic interconnection to the squeegee between said ball and said dispensing aberration (2). Therefore, said ball is free to rotate and can apply the content, already <The freeway between said lip (9) and said ball connects the content with the protruding part of said ball, the free way between said lip (9) and said hello is hereinafter called " product flow path ". The substi tional termi- nality of the leak-tight body is established immediately and automatically once the external force stops pushing said ball into the interior of said container. For this purpose, the flow path of the product is cut, interrupting the flow of the product from inside the container. Said ball pushed against said dispensing aperture achieves an interconnection in said substantially airtight container when draining when not in use. The flexible and elastic support means (4) according to the present invention allow to adapt the flow of the product from inside said container. In effect, the dimension of the track between said lip (9) and said ball (3) can be adjusted by the user by varying the external force exerted on said ball. Accordingly, the amount of flow of the product from the interior of said container can be controlled by varying the direction of said path. Specifically, a greater product flow can be achieved by pressing said ball deeper into said container. Furthermore, said flexible and elastic support means in combination with a per-mito flexible container further dispense or pour the product directly onto a surface by pressing on said hello and comprising compressing said flexible container. Figure 1 shows an embodiment according to the present invention. Said flexible and elastic support means (4) include a spring (5) located below said ball (3). Said spring presses said ball (3) against said dispensing opening (2) to achieve said substantial interconnection, being hermetic to the draining during the periods when said container is not used. By exerting a force F on said ball into said container, said spring elastically deforms and the flow path of the desired product is desired, as shown in Figure Ib. Said surface can be fixed separately on an internal part of said hollow body (1). Furthermore, said spring may be made of any possible material, such as, for example, metal or plastic. Said spring may have any possible shape, such as, for example, elicoidal or cylindrical. As another preferred embodiment according to the present invention, said flexible and elastic support means comprise the region opposite said dispensing opening at least one elastically deformable arm (6) that pushes. said ball against said dispensing opening (2) to achieve said hermetic leakage interconnection.

Said arm (6) can be bent at an angle OI (FIG. 2a) to achieve said elastic ablity. Preferably, or. is between 0o or 90 °. Preferably, said flexible and resilient resilient means comprise a housing (4a) that fits the container and defines said dispensing aperture at one end, as illustrated in Figure 2b. The adjustment of said housing to said container must be watertight, but said adjustment can be screwed or serrated to said container. Said threaded fit of said housing to said container may have the advantage of allowing an easy filling of said container to the user. Therefore, said flexible and elastic support means (4) can be made of a rigid or flexible housing, said housing supporting said spring (5) or said flexible arm (6) and can be inserted in said dispensing opening (2). As a preferred embodiment according to the present invention, such flexible and elastic support means (4) may include more than one of said elastically deformable arm (6) as in Figure 2b. And as a still preferred embodiment according to the present invention all said arms are connected to each other in a contact ring or single point of contact (Figure 2b, 7) of said ball). Preferably, such a single point of contact (7) with said ball is at the point of the ball that is most opposite said dispensing opening (2).

As an additional referral option, said flexible means and the support stub (4) may include-, in its region opposite said dispensing aperture (2), an interrupted rim (Figure 3, 8) where push the hello (3) when an external force is applied. This means that said interrupted edge prevents said ball from being pushed further inside said container. But since said r-edge is interrupted, that is to say said rim has at least one path permanently enclosed for the content, the path for the flow of the product is guaranteed. Therefore, said interrupted bead defines the maximum path of the product flow allowed by said flexible and elastic support means. Furthermore, said interrupted rim prevents said ball from being pushed inwardly with the risk of breaking said spring of said flexible and elastic support means. Such flexible and elastic support means (4) can be an integral part to or a separate part of said container (10). Said flexible and elastic support means may be made of injection resins (such as, for example, polypropylene, polyethylene, polyarylene, polyoxirnethylene) or elastomer polymers as thermoplastic elastomers (for example, polyurethane rubber, isoprene rubber, styrene butadiene rubber) ) or a combination thereof. In addition, it can be used to inject materials of two or more stages to achieve flexible, resilient support means having, for example, an elastic spring with a fixed attachment feature. Said t pa (20) is another essential feature of the present invention. Figure 4a illustrates said cover interconnected with said container (10). Said lid includes an upper wall (21) and a skirt (22) substantially perpendicular to said upper wall- ,. The interconnection means (30) permitting said lid to be connected to said container are part of said skirt, said container includes the flexible and elastic support means (4) described above in Figure 2b. Other flexible and elastic restraint means (4) are also possible as described above, for example in Figures la and 2b, said cover protects said ball against damage when said ball is not in use. connected said lid remains in a rest position in which the surface of said lid connected to said ball (hereinafter called "bottom" of the lid) does not touch any part of said ball. upwards by the pressure formed inside said container until said ball comes in contact with and finally presses on the lower part of said lid., said lid can also be useful to prevent the pressure formed inside said container from throwing said ball out of said container. According to the present invention said lid presses against said ball creating a free passage between said ball and said dispenerating opening (as shown in Figure Ib) only when .'O said cover of said container is connected or disconnected. To say that said lid is interconnected or disconnected means that said lid moves towards or from said rest position. As stated above, said free way is available when said lid presses on said ball. This happens when said lid is connected or disconnected from said container. This means that during this operation said container is maintained in its vertical position and the space of the head is located in the field above said container on the level of the product contained in said container. The "head space" is the volume of gas remaining in said container after filling between the high level of said product and the lip (9) of said dispensing opening (2). Consequently, the gases in said head space escape through said free path without also releasing the product. Therefore, said container is ventilated without creating dirt or debris. The availability of said free way is limited during a relatively small period. In effect, this availability is limited having a necessary time to interconnect and disconnect said lid (20) from said container (10). But it was observed that this period is sufficient to release at least a part of the pressure formed inside said container substantially decreasing the pressure difference between the inner part and the outer part of said container. It was further noted that the amount of pressure decrease obtained in this way is sufficient to prevent the product located around this ball from being expelled in an uncontrolled manner together with the release of pressure. Therefore, the dirt and the waste of the expelled product are avoided. The overpressure exists within said container is defined as the difference between the pressure inside said container and the pressure outside said container.The decrease of overpressure achieved when said cover is interconnected or disconnected from said container and creates said free passage is at least about 10%, preferably at least about 50%, preferably even at least about 90%, Specifically, it was observed that when the pressure formed within said vessel is about If it is necessary to lower this pressure to approximately 50 levels to avoid substantial negative results to be dispensed, the negative results when dispensing are mainly dirt and waste created when the gas inside the container is expelled during the dispensing of the product, as well as a burst of water. or described above, Figure 4a illustrates said lid (20) in the position This cap does not touch any place on said ball (3). Specifically, a gap (24) has an outer surface of said ball of the inner surface (31) of said lid. Therefore, said ball pushed against said dispensing opening (2) being the dispensing opening in a manner "> "? tight to gases. In the following, "gas tightness" means (gas can not pass through the interconnection between the inner part and the outside part of the container.) Alternatively, "gas tightness" can also mean in the proportion of The pressure (which can be released to the outer part * of the container through this interconnection (hereinafter referred to as the "Pressure Release Ratio") is smaller than the proportion of pressure produced in said container. therefore, a pressure is formed within said container, because the amount of gases that can escape to the outer part of said container is too small with respect to the pressure formed inside said container. an enlarged view the moment in which said lid of pressing said ball during the disconnection of said lid of said container The same happens in the inverse situation when said lid interconnects. ta with said container. This allows a greater flow of gases to pass through said free path 23 to the outside of said vessel, as described by the arrows, during the removal of the lid. As described above, said lid 20 stops pressing said ball 3 when said lid of said container 10 is interconnected or disconnected. One way of achieving this is to provide an interconnection means 30 between said lid and said container guiding said upper wall of said container. said cap to said ball to press on said ball whenever it is 2 '! It connects or disconnects the lid. It was observed that a possible way is to make said interconnection means include inclined screw threads (Figure 4C 30). The strings on said skirt 22 of said lid concur with other threads located on the outer surface of said body I below the aperture 2, it was discovered that the cords on the outer surface of said hollow body may be inclined to Such a way that said upper wall of said cover is put in contact with said ball (thu presses on said ball.) Such cords may be part of the outer surface of said container or part of the outer surface of said flexible and elastic supporting means. 4. An example of Figure 4C is shown, such a rope includes two ribs 32, 32 'that delimit a channel 33 in its middle part. Such a channel has such a dimension to fully accommodate the corresponding rope on said lid. said channel at one end 33A and closed at the opposite end by the wall 34. Preferably, said wall 34 connects said two ribs 32, 32 'to each other. ho container, the rope of said lid has to enter the channel from its open end. The open end of said channel 33 is in a lower position with respect to the closed end when said container is in its vertical position. This means that said lid has to be pressed downwards until the cords can enter said channel.

As a preterm option The rib 32 above said channel 33 closest to said aperture 2 further includes an inclined portion 35. The inclination of said inclined portion is directed to said aperture 2, as illustrated in the Figure 4d. This especially facilitates the interconnection to said channel 33 of the cords of said lid. In effect, said inclined portion 35 guides the cord of said lid 20 back to said channel when said container is closed again. Consequently, it is easy to use a rotational movement to interconnect said lid 20 with said interconnecting windows. Without having to push said lid in. As another preferred option, the rib 32 'below said channel 33 very far from said opening may further include a second inclined portion 46. Again, the inclination of said second inclined portion is also directed towards said opening 2 as illustrated in Figure 4D this second inclined portion 36 especially facilitates the disconnection of said channel 33 from the cords of said lid In effect, said inclined portion 36 forces said lid upwards helping to lift said lid when said lid and said container are disconnected, then the plane P (Figure 2B) is the plane tangent to the highest point of said ball when said The owner is in his vertical position. Furthermore, dt is the distance between said chord of said lid and said upper pairs (Figure 2B, 31) on the lower part of said lid, ". GT and dc is the distance between said open end (Figure 4C, 33A) and said plane P "Therefore, when the distance dt is less-than the distance dc ensure that said upper wall-presses on said ball when the rope of said lid it enters said open end of said channel. The difference = (dc d-t) may be less than or equal to the maximum displacement of said fio within the said vessel allowed by said flexible and elastic support means. Said cover is further rotated to the left until the rope of said cover is stopped by said wall (Figure 4C, 34). In this position said lid closes said container. Said lid presses on said ball also when disconnected from said container. In effect, we rotate said lid to the right, said lid moves from the closed end of said open end of said channel, that is said lid moves downward from said closed end to said open end. Thus, such lid can press again on said ball and open said free path 23 between the inside and outside of said container. Said lid 20 including child-resistant features is another possibility of achieving a free passage 23 when said lid is interconnected and / or disconnected from said container. An example is shown in Figure 6. In this case, the rope 41 of said lid has to be pushed inward first to said channel 23 of the space 42 so that said rope 41 of said lid is at the open end 33A and to separate said lid of said interconnection with said container. In the event that said rope 41 of said lid is rotated - without being pushed inwardly, said cord 41 is prevented from being rotated one more by the wall 43. Next, a "gas tight lid" means a cover that substantially prevents any escape of gases to the outside of said container. In the event that said lid 20 is not gas tight, the gases passing through said free wall are omitted directly into the external atmosphere, for example through the area of the screw cords. the flow of the gases to the outside of said container, said lid preferably can be provided with at least one hole, said hole being a hole made through the thickness of said lid.The situation is different when said layer 20 closes said container 10 in a gas-tight manner In this case, possible escape routes have to be provided for the gases going through said track 23. Preferably, said gas-tight layer can be useful when said interconnection between said ball 3 and said opening 2 allows a small proportion of pressure release In fact, it was observed that the gases passing through interconnection between said ball and said opening can force out some ca ntity of the liquid product content. Therefore, said gas tight lid prevents dirt and waste. The simplest way is to let said gasses escape first within any free volumes (l ~ FIGURE 41! A) that exist between said t and said container. Then, these gases in the volumes (Figure 4B, n) can be completely released after said lid is completely disconnected. This n is an ideal solution when the volumes (Figure B, A) do not provide enough space for the gases coming from the interior part of said container. Another gas-tight cover 20 'is shown, for example, in Figures 5A and 5B. Preferably, said cap 20 'further includes a sealing ring 25. Such sealing ring is a continuous wall extending from the interior surface of said upper wall 21 and which is substantially parallel to said skirt 22. Said sealing ring surrounds completely the outer surface of said hollow body 1 in the upper portion of said container 1. Preferred blernente, said sealing ring surrounds the outer surface of said hollow body exactly below said lip 9. Most preferably, said sealing ring surrounds the surface outside said housing 4A exactly below said lip 9. Said sealing ring achieves a leak-tight connection to the outer surface of said hollow body when said lid is in said rest position. As described above, said lid moves downwardly pressing on said ball when said lid is disconnected. In this way, such sealing ring can be pushed down on a location of said outer surface of said hollow body where said sealing ring no longer achieves a gas-tight interconnection. Accordingly, said gases emitted through said rail 23 can finally escape to the outside of said vessel. This exhaust can be facilitated with at least one hole located under said sealing ring <; When the container is in its vertical position. One embodiment achieves the ventilation mechanism described above is shown in Figure 5A, the upper portion of said container further includes at least one cavity 27 such cavity is located on the outer surface of said hollow body 1 below said ring sealing said lid 20 'when said lid closes said container in its rest position Such a cavity can be a continuous channel all around said outer surface of said hollow body It is also feasible to have more than one cavity around said The outer surface of said hollow body is separated from one another, preferably, all the cavities are located at the same height, said cavity can be formed by producing the thickness between the inner and outer surface of said hollow body. It is a concave bent portion of the wall of said hollow body viewed from the outside of said container. The gases escape from inside said container to be emitted outside said container. In effect, when said cover 20 'of the container is disconnected, such an indigo Sealing is pushed down towards said cavity. And once on said cavity said sealing ring no longer ensures a gas-tight interface with the upper portion of said container, ie there is no interstice of free space between said cavity and said sealing ring. Accordingly, gases passing through said free path 23 when said ball is pressed downwardly by said cap escapes through this gap between said cavity and said sealing ring to the outside of said container. The same happens when said lid is interconnected on said container. Another possible embodiment that achieves the same ventilation mechanism as described in Figure 5A is illustrated in Figure 5B. In this case said cavity 27 is replaced by at least one projecting part 28. This means that the projecting part 28 is located on the outer surface of said hollow body l below said sealing ring 25 of said cover 20 'when said cover closes said container in its repose position. It is again feasible to have rnae of a protruding part around said outer surface of said hollow body independent of one another. Preferably, all the projecting parts are located at the same height. Said protruding parts are not connected to each other. Otherwise no way would be available for the escape of gases. Such a protruding part can be formed by increasing the thickness- between the inner and outer surface of said gas. hollow body. Alternately, said protruding part may be a convex bent portion of the wall of said hollow body viewed from the outside of said container. As before for said cavity 27, said projecting part 28 allows the gases to escape from the interior of said container to be emitted outside said container. In effect, when said lid 20 'is disconnected from said container, said sealing ring is pushed down towards said protruding part. And an envelope on said projecting part, said sealing ring no longer ensures a gas-tight interconnection with the upper portion of said container, ie there is a clearance gap between said sealing ring and immediately around it. said outgoing part. In effect, said sealing ring is raised at least partially by said projecting part, as described in Figure 5C. When more than one of said protruding parts is present said sealing ring may be completely raised, whereby the gases escaping from the interior of said container are emitted through the free space between said spaced apart portions. Accordingly, the gases that pass through said free path 23 when said ball is pressed downwardly by said layer escape through this free space when said protruding part and said sealing ring to the outside of said container .. The same thing happens when said lid is attached to said container.
